Perhaps structural changes in the way politicians are elected and retain office would have some positive long term effects. I imagine if it was possible to hold a direct-vote referendum on the current sitting president mid-term would hold their feet to the fire at least a little bit. Also, prohibiting advertising by political campaigns (TV, print, all of it) coupled with state-sponsored, mandetory debates between presidential candidates might force a real debate about real issues.

And assuming we agreed that those changes would be beneficial to the political system, how might we go about achieving those reforms?
